Distribution

C. gunnari is only found in the Antarctic, most southern region of the world, but is widely distributed south of the Antarctic convergence over shelf areas of sufficiently shallow habitat surrounding sub-Antarctic Islands. Their main area of distribution in the Atlantic Ocean is the Scotia Arc from South Georgia Island in the north to west of the Antarctic Peninsula at approximately 67°S. Their area of distribution in the southern Indian Ocean is around Kerguelen, Heard, and McDonald Islands (Kuhn 2006).
